to sample the signal at the Nyquist rate in order to realize real-time WBSS. When the spectrum to be sensed is very wide, this may bring a challenge to hardware implementation as high-speed analog-digital converters (ADCs) are energy-intensive and too costly for practical systems. Thus, sub-Nyquist sampling-based techniques which have the potential

Shannon-Nyquist sampling theorem is the most fundamental and well known for transforming a continuous-time band-limited signal into its discrete-time form. Over the years, many other methods have been developed for the same. The sampling frequency i.e. the number of samples taken per second, is one of the important characteristics of the sampling process. Since high sampling frequency is very ...
Next, one digitized sampling sequence will be obtained from the ADC that runs at sub-Nyquist rate. To elaborate, assume x(t) exhibits identical waveform during each excitation, if the triggering level remains constant, then the triggering positions at the waveform should be the same. Yet the sub-Nyquist rate clock that controls the ADC will not
typically a multiple of 13 MHz. Sub-Sampling Nyquist's sampling theorem states that if a signal is sampled at least twice as fast as the highest sampled frequency component, no information will be lost when the signal is reconstructed. The sample rate divided by two (Fs/2) is known as the Nyquist frequency and the frequency range
MUSE (Multiple sub-Nyquist sampling encoding), was a dot-interlaced digital video compression system that used analog modulation for transmission to deliver 1125-line high definition video signals to the home. Japan had the earliest working HDTV system, which was named Hi-Vision (a contraction of HIgh-definition teleVISION) with design efforts going back to 1979.
The Multiple Sub-Nyquist Sampling Encoding system was developed for the realization of HDTV satellite broadcasting using a single 12-GHz WARC-broadcast satellite (BS) channel. In order to confirm the picture and audio qualities of the received HDTV signal via BS, transmission experiments have been carried out. The resulting picture quality, using the reception antenna of diameter 0.75 m, was ...

In this letter, we propose new sub-Nyquist sampling schemes for multiple sinusoids, which require fewer number of samples than previous works. Since it is impossible to resolve the frequency ambiguity using a single sub-Nyquist sample sequence, an additional sampling channel is used to determine the correct frequencies. First, a time-staggered sampling system, with the staggered time less than ...

The Nyquist-Shannon sampling theorem states that if all that you know about a signal is that its highest frequency is no greater than B, then if you want to sample the signal without any loss of information, you must sample it at a rate that is greater than 2B. If we call the rate at which we sample Fs, then we find that B <; Fs/2, and Fs/2 is called the Nyquist frequency. For a simple proof ...

A single-chip LSI has been developed to decode audio signals which are multiplexed into MUSE (multiple sub-Nyquist sampling encoding) signals for transmitting HDTV (high-definition television) signals. Because the LSI requires just a few peripheral parts (such as two RAMs and one voltage-controlled oscillator circuit), use of the LSI can reduce the size of the MUSE audio signal decoding ...

Multiple exponentially damped sinusoids (MEDS) signals have been widely applied to the fields of speech analysis and nuclear magnetic resonance imaging systems.
